Abstract : This report summarizes the significant contributions from a research program sponsored at Argonne National Laboratory by the Air Force Wright Aeronautical Laboratories, Advanced Propulsion Division. The objectives of this study were to develop advance computational techniques and physical models for calculating the multidimensional flow and combustion process in subsonic ramjet and ducted rocket configurations. A number of significant accomplishments were made during the course of this study. These include: (a) development of efficient solution techniques for subsonic, elliptic fluid flows; (b) application and assessment of the two-equation turbulence model to swirling and nonswirling flows in a sudden expansion geometry; (c) analysis of combustion processes in a prototypical ducted rocket configuration. Keywords: Ramjets; Ducted rockets; Combustion; Computer models.
